Great messaging tool for start ups

Comments: I've had a great experience using Slack, it's easy and fun to use, easy to configure and overall a powerful tool for the people that look for this type of messaging application. It's not for everybody but it's worth trying.

Pros: Slack has the vibe of an application that's cool to use, it has a very 'young' vibe to it. For me, it feels like a great application for start ups or small teams to use because the degree of customization of the workspace is immense. The application is also quite easy to configure at the start, with many features that can be added later in the process, depending on the need. It's a tool that has the common features that a messaging application would have (private conversations, group conversations, topic based conversations, private / public channels, integration with other useful applications) while also integrating bots that can be useful and fun to play with. Both can be entirely programmed by the users so they offer pretty much whatever functionality the creator wants to achieve - some can also be found online, already created and free to use, for the people that don't want to bother creating their own.

Cons: I would say that a con for this software would be that it's sometimes hard to take serious. Young people may be excited to use Slack and create their own bots but some professionals may not find this as a selling point for them and it may seem childish. This is not necessarily a minus that the application has, but it is the type of application that's not for everybody.

It's anything but Slack

Comments: We started using Slack in order to not have to talk to each other... Actually to be fare, we're spread across 4 floors and multiple offices (sometimes people work from home) so Slack gives us a way to communicate across multiple channels looping in relevant people that need to be updated on specific projects. The ability to be able to quickly jump onto a call or post images and video easily greatly enhance communication. Slack is open on all our computers (Mac and PC) all day every day and is key to getting things done! And you don't have to 'talk' to Dave at his desk anymore so no 20 minute conversations on the virtues of staples over paperclips, WIN!

Pros: It's so easy to set up an account, add your teammates, create your channels and assign/amend and remove access for who can see what. Also found loads if integrations with other software packages useful. I didn't much like the browser version but the desktop and mobile apps work a treat. Being able to set 'out of office' or 'end of day' do-not-disturb times really helps you to not get woken up in the middle of the night by Dave who had a brainwave on how to better stack the free peanuts in the break-room (we all have a Dave).

Cons: I initially had a bit of a blond moment (is it politically correct to say that? Gulp) when I first started using the web version of the app. I didn't really like it and it took me a while to figure out that there was in fact a desktop and mobile version that were much nicer to use (as mentioned in the Pros section).

Love it. Slack-ing off @ work

Comments: It has offered a more comfortable work life and the UX seems to have that as a guiding principal. It works well and has a wonderful host of API's that greatly extend functionality of the software.

Pros: It makes Microsoft Teams or whatever they call it this year obsolete. It's like an intra-office Reddit for us. Hilarious but still very productive.

Cons: That it defaults to trying to update via windows store. Which is not accesible via group policy. Forcing an manual install every time.

Comments: Slack improves correspondence among colleagues. In spite of the fact that it doesnot supplant the need of email yet yes it clearly reduces unnecessary inside messages Slack stays a standout amongst the best group informing applications since it offers more than some other application in this classification. For a variety of devices and platforms, Slack is available: mobile Mac, Windows, Linux, Web, Android, iOS, and Windows.
It is a cloud-based tool in real time, so you need an Internet connection to use it regardless of which app you have.

Pros: What I truly like is to discover individuals and ping them and begin a transformation. Most significant, you can share records, photographs, URL, gifs (Very significant), in a solitary spot.
Making joint effort simple and something to appreciate.
at the point when significant data is imparted to other application it gets lost and there is no record of it. With the slack channel, the data is put away and can be utilized as references Slack makes it workable for its clients to have numerous alternatives of getting informed. The best component, as I would see it, is the place somebody can "@" you in a message or a post.

Cons: Below are some points which I least like in Slack: Video calls are just bolstered in the work area applications and Slack for web in the Chrome program. In the event that you join a call from a cell phone, you get sound as it were. So also, screen sharing just works from the work area applications, what's more, sharing control of screen sharing just works in the Mac and Window work area applications (not Linux). From the web application in Chrome, you can watch on the off chance that another person utilizes screen sharing, yet you can't start it. There is also no option for downloading conversations to create a hard copy record (for minutes of meeting, etc.). No File Preview: If you could preview a document without downloading it first, it would be nice. But Slack does'nt have this feature.

Slack is the best chat app, but don't use it as a wiki or PM tool

Comments: Slack effectively solves our need for real-time communication. We use the chat, voice and video calling options. It's a great tool and better than most other chat alternatives, but don't be tempted to use it to manage projects, store documentation, or give structure to files. You'll soon be overwhelmed by the lack of structure.

Pros: I love Slack's ease of use and simplicity. New users can get up to speed quickly and begin using fun features like @mentionds, /gifs and :emojis: The file attachments and search speed are well done.
Slack's real power is in all the integrations, so I love being able to hook up a dozen or so apps and collect all my notifications in one place. Also, the freelancer community has embraced Slack because of their free/cheap plans, so it's very convenient to keep in touch with a variety of contractors by just inviting them (since most already have their own Slack plans).

Cons: Slack isn't great at providing structure to your work-life. The #channel structure does aid in some structure, but Slack's support for threads is awful--they don't make any sense, and most people can't figure out how to use them. These deficits are offset somewhat by searchability, but for the most part you'll just be scrolling through endless conversations if you want to find a particular piece of info.
